A sand sculpture in the style of Mount Rushmore has been created on Weymouth Beach from 40 tonnes of sand. The sculpture features David Beckham, Joey Essex, Harry Styles and Frankie Cocozza, who were all featured in a best and worst celebrity hair poll carried out by Lynx. Beckham topped the poll, while Cocozza had his unruly mop voted as Britain's least favourite celebrity male hairstyle.Picture: Lynx
